The aim of this research was to investigate on bolted joints characterized by steel screws and aluminum nuts by means of numerical simulation. 2D and 3D CAD/FEM parametric models were developed in order to determine the preload distribution in joints with and without a Wired Threaded Inserts (WTI), so as to compare the trend of the stress distributions and the amount of load applied to each thread. The operating mechanisms and the effectiveness of a WTI were investigated in a parametric study by means of which the most important factors of the joint (materials, class, diameter, Engagement Ratio (ER), tolerance bands) were varied.

Abstract
The aim of this research was to investigate on bolted joints characterized by steel screws and aluminum nuts by means of numerical simulation. 2D and 3D CAD/FEM parametric models were developed in order to determine the preload distribution in joints with and without a Wired Threaded Inserts (WTI), so as to compare the trend of the stress distributions and the amount of load applied to each thread. The operating mechanisms and the effectiveness of a WTI were investigated in a parametric study by means of which the most important factors of the joint (materials, class, diameter, Engagement Ratio (ER), tolerance bands) were varied.File in questo prodotto:
